3 Claims. (Cl. Mil-45) This invention appertains to new and usefulimprovements in automobile headlights and more particularly to aheadlight which incorporates means for eliminating the blinding glarewhich frequently causes accidents alt night.

The principal object of the present invention is `to provide a headlight`structure of substantial conventional construction wherein a lightreflecting baiile is installed to cause internal deflection of the lightto the end that the light will be projected from the upper portion ofthe reflector exclusively.

Other objects and Iadvantages of the invent-ion will become apparent tothe reader of the following speccation.

In the drawings:

Figure 1 represents a vertical sectional view through the headlightstructure.

Figure 2 is a front elevational View of `the head- 'ght case andreflector with the lens removed.

Figure 3 is a perspective view of the adjustment boss.

Figure 4 is a side elevational View of the deilector adjusting means.

Figure 5 is a vertical sectional view .througha modiiied form of theinvention.

Figure 6 is a front elevational view of the structure shown in Figure 5.

Figure 7 is a fragmentary perspective view of the adjusting means.

Referring to the drawings wherein like numerals designate like parts, itcan be seen in Figure 1, that numeral 5 represents a headlight casewhile numeral B denotes a parabolic reiiector. A lens I is mounted atthe front side of the case 5, while at the center of the reflector andcase is a socket 8 for a bulb 9.

A slotted raised bracket I is secured to the lower portion of thereflector 6 and has the lower portion of a arcuate post Ill dependingthereinto. The lower portion of the post II has laterally disposedtrunnions I2 which extend into bearing formations I3 on the said bracketI0.

A horizontally and vertically curved deiiector Ul is secured to the postH by suitable means I5. The convex side of the deecto-r I'II opposes theconcave side o-f 'the reflector 6. The reector It is adjusted byadjusting means |16 to properly set the deilector I5 with respect to thelamp 9 so as to throw .the beam upwardly against the upper portion ofthe reect-or 6 and outwardly, tothe end that there will be no upwardglare from the lower portion of the reflector 6.

A hollow boss I'I is attached to .the lower portion of the case 5 andforms part of the adjusting means I6. This bos-s I'I has attaching earsI3 and a radial arrangement of teeth I9 with which teeth 20 on a knurlednut 2l can engage. As shown in Figures 1 and 4, a threaded stem 22extends through an opening 23 in the boss I1 and thro-ugh the radialarrangement of teeth I9 and has a laterally disposed inner end portion24 which is disposed into the lower portion of the post I I `and adaptedto extend a slight distance beyond, at .which extremity the laterallydisposed portion 2-4 is circumferentially grooved as at 25 to receive akey or the like. Thus the post Il is pivotally connected at its lowerend to the stem 22.

The stem 22 has the adjustable collar 26 `thereon, between which and thetoothed end of the hollow boss I1 a coiled compressible spring 21 isinterposed.

KIt can now be seen .that the nut 2| canbe fed inwardly or outwardly onthe stem 22 to properly adjust the deflector I4 to set the beam at thedesired angular-ity.

In Figure 5 the deiiecto-r Na is secured to the front side of thearcuate-shaped post l Ia by suitable -securing means Ida. The adjustingmeans generally referred to by numeral [6a is of the same constructionas the `adjusting means I6 and the lamp 9a is mounted behind thedeflector Ma as in the form of the invention shown in Figure 1.

However, in .the form of the invention shown in Figure 5, a socket 28 ismounted on the forward concave side of a, deflector Ma for carrying abulb 29. Thus the power o-f the headlight can be increased by thepro-vision of .a bulb behind the deflector Illa yand one at the front ofthe same. Furthermore, due to the location of the deflecltor Ma withrespect to the lamp 9a and the position of the lamp 9a with respect tothe deec'tor Ma, there can be no reection of light from the lowerportion of the main reflector 6.

While th'e foregoing specification sets forth the invention in speciicterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without `departing from the spirit andscope ofA the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A light projector comprising a. reflector, a bulb mounted in front ofthe reflector, a light deflector in front of the bulb, a bracket on thelower por-tion of the reiiector, a post on which the deiiector ismounted, said post having its lower portion pivotally mounted on thebracket, a threaded member extending from a portion of the post belowits fulcrum point and extending through a portion of the reflector, aboss on fthe outer side of the reflector through which the threadedmember extends, and a nut on the outer end of .the threaded memfberoperative against the boss to adjust the position of the post yanddeflector.

2. -A light projector comprising a reector, a

l :bulb mounted in front of the reflector, a light deflector in front ofthe bulb, a bracket on the lower po-ntion of the reecftor, Ia post onwhich the deflector is mounted, said post having its lower portionpivotally mounted on the bracket, a threaded member extending from aportion of the post below its fulcrum point and extending through apontion of the reflector, a boss on the outer side of the reflectorthrough which the threaded member entends, a nut on the outer end of thethreaded member operative against the boss to adljust the position ofthe post and defle'otor, a collar on the threaded member, and acompression spring interposed between the collar and the inner side ofthe boss.

3. A light projector comprising a reflector, a bulb mounted in front ofthe reflector, a light defieotor in front of the bulb, a bracket on thelower portion of the reector, a post on which the deflector is mounted,said post having its lower portion pivotally mounted on the bracket, athreaded member extending from a portion of the post below its fulcrumpoinlt and extending through a portion of the reflector, a boss on theouter side of the reflector through which the threaded member extends,Iand la nut on the outer end of the threaded member operative againstthe boss to adjust the position of the post and deflector, said nut andopposed surface of the boss being provided With meshable teeth.
